Abstract: PURPOSE:To form precisely and uniformly the hardening finish in the peripheral and transverse directions of a member which rotates axially by heating the prescribed peripheral surface of said member by a heating coil then cooling quickly the member by plural streams of the fluid which are divided periphery and ejected alternately in opposite directions. CONSTITUTION:The member W is axially rotated and the race track surface on the inside periphery thereof is heated to the prescribed hardening temp. over the prescribed width by the heating coil C. The cooling fluid is thereafter supplied through supply pipes Ha, Hb to cooling mechanisms Ja, Jb and is injected from the injection ports S thereof to cool quickly the heated peripheral surface of the above-mentioned member, by which said surface is subjected to one-short hardening and the prescribed hardened layer is formed on the peripheral surface of the member W. The holes S are formed alternately with each of the mechanisms Ja, Jb in the opposite directions over the entire periphery so that the jets of the cooling fluid flow away by flushing quickly on the surface to be heated of the member W. The hardened layer Wh is thus precisely and uniformly formed down to the substantial depth.

Title: Heat exchanger for high-efficiency cooling
Inventor: OTSUKI SATOSHI
IPC: F25D3/10
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To prevent the cooling capacity from being lowered even when the liquid level of liquid refrigerant falls with its vaporization by providing, at the bottom of a refrigerant vessel having an insulating structure inside which liquid refrigerant is stored, a heat-exchanger tube having a heat-exchange part which is wound in a flat spiral. SOLUTION: A heat-exchange part 31 wound in a flat spiral of a heat- exchanger tube 3 is placed at the bottom of a Dewar vessel 1. The heat- exchange part 31 is in contact throughout with the lower part of the liquid N2 . The liquid level of the liquid N2 gradually falls with its use from the state of full tank by heat exchange. Since, however, the whole of the heat-exchange part 31 is on one and the same plane, the fall of the liquid level does not cause the heat-exchange part 31 to be exposed so that a high heat-exchange rate is obtainable. Therefore, a high cooling capacity can be maintained in a stabilized state.

Filed: 1994-01-20
Abstract: PURPOSE:To stably amplify a signal extending over a wide frequency range in spite of load impedance by interposing a buffer resistor between the collector of a transistor and a load in series, and grounding the base of the transistor. CONSTITUTION:The buffer resistor 16 is provided with a comparatively low buffer resistance value, and the value is set, for example, at 500OMEGA, and it is connected between the collector of the transistor 1 and the load 14. When the resistor 16 is added, the center point locus 26 of the stable circle of knurl is curved in the upper right direction from a start point Q, and is moved in a direction to separate from a Smith chart. When the resistor 16 is provided with a specific value, a frequency so as to come in contact with the outermost peripheral circle 27 of the Smith chart exists. Such value is shown in point A, and it is the critical resistance value of 1800MHz of the resistor 16. Therefore, the stable circle can be prevented from being intersected by separating from the Smith chart completely, which attains absolute stability for the amplifier.

Abstract: PURPOSE:To prevent the generation of white smoke from an exhaust cylinder by providing an air bypass passage connecting an exhaust port to an air supply port in parallel to an air fuel supply passage of the combustion part and also providing a device for adjusting the opening degree of the passage area in the bypass passage. CONSTITUTION:By detecting the combustion state and the concentration of exhaust gas, a motor 19 is actuated, the opening degree of a valve 20 is adjusted, and a predetermined combustion state is maintained.
